I quit 17 months ago.Used the patches for about 6 weeks and,contrary to what some are saying,they helped.The patches only took the edge off though.I tried and failed several times in the past and only succeeded when I wanted to quit worse than I wanted to smoke.It was a real B#####.I started riding when I quit.The first ride was about 4 miles and I felt like calling 911 when i got done.That was in March and by about Sep. I could do 40 mi. in a day.I'm hoping to ride a century next month.I'm 42 and can look at some folks i know that are 52 and see some whose health is permanently ruined by smoking.I didn't want live like that.I wanna be the guy who takes a 6mo. bike tour in his 70's.
